from ivtv-0.4.0/doc/video-quality.txt:
--- cut here ---
dnr_mode:
0: spatial and temporal noise removal filters
1: temporal only
2: spatial only
3: no noise filter
dnr_spatial:
0..16: 0=no filtering 16=strongest filter
(horizontal only, smoothing/lowpass)
dnr_temporal:
0..16: 0=no filtering 16=strongest filter
(inter-frame (time dimension), averaging)
--- cut here ---
so...
$ ivtvctl -c dnr_mode=3
$ ivtvctl -c dnr_spatial=0
$ ivtvctl -c dnr_temporal=0
The MPEG-2 settings I am curious about are:
framespergop
gop_closure
bframes
